It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-50234 in the wild and no public exploit code.\n\nAffected product: Hancom Office. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-50234/ (Markdown: https://insights.sbomify.com/CVE-2023-50234/index.md)","id":"CVE-2023-50234","markdown":"https://insights.sbomify.com/CVE-2023-50234/index.md","name":"CVE-2023-50234","record":{"aliases":["GHSA-6f5p-4w3q-jr7c"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Hancom Office Cell","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by tricking users into opening malicious XLS files in Hancom Office Cell due to a stack-based buffer overflow.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"office_cell","vendor":"hancom"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Hancom Office Cell XLS File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hancom Office Cell.

The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer.
